Abstract

The present invention relates to a melody toothbrush that allows children to brush for a set amount of time by auditory and visual means, and to adapt naturally by providing young children with an interest in brushing. In the toothbrush comprising a head, the groove is formed in the upper surface of the handle to insert the digital clock, the melody chip and the switch, the internal hollow in the battery to connect the switch, the digital clock and the melody chip electrically When the handle is gripped for brushing, the switch is switched to configure the digital clock and the melody chip to operate for a predetermined time.

Description

Melody Toothbrush {MELODIC TOOTH BRUSH}

The present invention relates to an oral toothbrush, and more particularly, to a melody toothbrush provided with a clock and a melody chip on the handle portion of the toothbrush to inform the brushing time.

Food intake is sandwiched between the gums in the oral cavity after ingesting food. To prevent tooth decay by removing food residues between teeth and gums through brushing after meals.

Brushing begins at about 3 years of age by the parents' education. The initial brushing education begins with parents acting directly on young children. Will be done.

However, the younger they are, the less concentrated the children's concentration is. In particular, the concentration in brushing is very low and most young children finish brushing in a short time.

Therefore, it is necessary to find a learning method that provides young children with an interest in brushing and induces them to brush for a certain period of time.

In addition, it is not clear to adults how much time they need to brush their teeth, and most of them finish brushing in a short time, so they cannot brush for the time required by dentists to clean their mouths.

The present invention has been made in view of this point, and an object of the present invention is to provide a melody toothbrush that induces children to brush for a predetermined time by auditory and visual methods.

Another object of the present invention is to provide a melody toothbrush that can adapt naturally to children by providing an interest in brushing.

In order to achieve the above object, the present invention provides a toothbrush including a handle, a neck, and a toothbrush cap. By internally connecting the switch, the digital clock and the melody chip to hold the handle for brushing, the switch is switched so that the digital clock and the melody chip are operated for a predetermined time.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing a toothbrush of the present invention, Figure 2 is a cross-sectional view of Figure 1 showing the internal structure of the toothbrush, Figure 3 is a circuit diagram showing an electrical connection state of the present invention.

The toothbrush indicated by the reference numeral 1 as a whole includes a head 2 having bristles, a handle 3 having a space therein, and a neck 4 connecting the head 2 and the handle 3.

The handle 2 is formed with recessed grooves 5 into which the digital clock 11, the melody chip 12, and the time switch 13 are inserted, respectively, and the recessed grooves 5 are formed in the handle 3. Communicate with the unit to make electrical wiring.

A battery 10 accommodating groove 6 is formed at the edge of the inner space of the handle 3, and the opening of the accommodating groove 6 is provided with a removable cover 7 to replace the battery.

Furthermore, since the toothbrush 1 is always in contact with water, it is desirable to prevent the short-circuit of the electrically connected terminals from being inevitably waterproofed. It is preferable that the inside space and the outside are sealed between the parts 5, and in the case of the melody chip 12, the upper surface of the chip is epoxy treated. The melody chip 12 may use various kinds of music continuously for a predetermined time, or use an alarm chip or a voice chip that sends out an alarm when a predetermined time elapses.

If you use a voice chip, it is a good idea to enter a variety of comments to give children a learning effect or interest in brushing.

For example, you can insert a comment on the toothbrush of the tooth over time, or "clean the teeth", or "clean well" when the brushing time is completed.

The time switch 13 is pressed when the handle 3 of the toothbrush 1 is held by a contact switch to apply power to the digital clock 11 and the melody chip 12 for a predetermined time and to short-circuit the power. Here, the timing of the time switch 13 can be set variously at intervals of 30 seconds, 1 minute, and 2 minutes.

The digital clock 11 is interlocked with the time switch 13. When the contact of the time switch 13 is connected, the digital clock 11 is reset to count the time in the initialization state. It is preferable that the count time of the digital clock 11 and the melody chip 12 coincide with the timing set in the time switch 13.

The embodiment has described an example of a segmented digital clock, but as another embodiment, a liquid crystal graphic device can be used as a digital clock.

Liquid crystal graphic elements are liquid and exhibit optically crystal-like properties, and time can be measured by color change.

For example, if a plurality of columns of 30 seconds or 1 minute are formed and time elapses, the time can be represented by encroaching the area of the column.

In addition, the present invention may be used semi-permanently by allowing the head 2 to be replaced when the bristle is damaged by the detachable type in which the handle 3 and the head 2 of the toothbrush 1 are separated.

As described above, the present invention installs a clock or melody chip on the handle of a toothbrush, and when holding the handle, counts the time for a certain time or sends out music, so that children or adults can brush for a certain time required by the dental association. To make it possible.

Moreover, when brushing children, the melody is sent out so that they can be motivated and interested in brushing, which helps to prevent tooth decay.
